IMPROVEMENT IN WATER-WHEELS.

Specification forming part of Letters Patent No. 19 1,605, dated J one 5, 1877; application filed May 21, 1877.

To all whom it may concern Be it known that I, Isaac MALLERY, of Dryden, in the county of Tompkins and State of New York, have invented a new and Improved Water-Wheel, of which the following is a specification:

This invention relates to downward-discharge turbine water-wheels and the nature of my invention consists in the employment, in combination with a stationary chute-case andan independent adjustable frame, of a series of gates, which are pivoted to this frame and adjustable to the periphery of said case, as will be hereinafter explained.

In the annexed drawings, Figure 1 is a section taken vertically and centrally through the improved wheel. Fig. 2 is a side view of the wheel, with part of the chute-frame broken away to show the chute-case. Fig. 3 is a top view of the wheel, partly in section. is a side View of the bucket-wheel.

Similar letters of reference indicate corresponding parts.

The letter A designates the bucket-wheel, formed of curved and inclined buckets arranged around a hub, and applied to a capring and a skirting, as shown in Figs. land 4. This wheel is keyed on a driving shaft, B, stepped on a bridge, 0, and passed up through a tubular sleeve, 0 which is cast on the top of a cylindrical chute or guide-case, D. This case D is rigidly secured to the base or bedframe E, and constructed with oblique issues I), which direct the currents .of inflowing water against the buckets of the wheel A, as indicated by the arrows in Fig. 1.

G designates a circular frame, which surrounds the case D, and is constructed with Fig. 4

arms radiating from a central hub, c, that is free to turn on the stationary sleeve a. This frame G is adjustable about its axis by means of a rack, d, and a pinion spur-wheel, d, which latter is on a shaft that is borne by an arm, H, fixed to the sleeve a of the chute-case.

The upper and lower rings of the frame G are connected together by obliquely-arranged blades f, which are applied to offsets of the rings, thus forming mouths, through which the currents of water flow.

J J designate the adjustable gates, which are constructed with tapered flanges k k on their upper and lower edges, and also with two ears, l 1, near their curved ends. Each gate J is pivoted between the offsets of the frame G at i i, and its free end is adapted to impinge against the periphery of the case D, to which it can be adjusted by means of setscrews n n tapped through the ears I l, and bearin g against the periphery of the frame G.

By means of the screws n the free ends of the buckets J can be adjusted so as not to leak, and at the same time not to cause no due friction on the chute-case.

Having thus described my invention, I claim as new and desire to secure by Letters Patent The adjustable gates J, constructed with flanges k k and set-screws n n, and pivoted between the rings of adjustable frame G, in combination with the chute-case D and a Wheel, A, substantially as described.
